About this calculator
Calculate the great-circle distance between two latitude/longitude points using the haversine formula, useful for flights, sailing, and trip planning.
Frequently Asked Questions
What is the haversine formula?
It's a formula that calculates the shortest distance between two points on a sphere given their latitude and longitude, accounting for the Earth's curvature.
Is this the same as flight distance?
This gives the great-circle (as-the-crow-flies) distance. Actual flight paths may vary slightly due to air routes, weather, and airspace restrictions, but this is a very close approximation.
Where can I find latitude and longitude for a location?
You can find coordinates using most mapping apps like Google Maps by right-clicking or long-pressing on a location.
